Subject: [PATCH v3 0/4] Add display support for Fairphone 4

Introduce the bindings and panel driver for the LCD panel with the model
number 9A-3R063-1102B from DJN which is using the HX83112A driver IC. It
is used on the Fairphone 4 smartphone.

Then we can add the panel to the device dts and also enable the GPU.
